Since this directory is DEPS'ed in by some other repositories (webrtc, pdfium, v8, etc), it should be kept as self-contained as possible by not referring to files outside of it. Some exceptions exist (
//third_party subdirectories), but new dependencies tend to break these other projects, and so should be avoided.
//build should be landed in the Chromium repo. They will then be replicated to the stand-alone build repo by the gsubtreed tool. Note: You can find all directories already available through gsubtreed in the list of all chromium repos.
//build/config - Common templates via
//build/toolchain - GN toolchain definitions.
